Sum Values on 2 Where Clauses

Question

Hi, sorry to trouble, i havent got any data within a database or anything, just thinking about some work that i might have to do, so trying to get a head start. Was wondering how i would sum values in a column but with 2 where clauses. For example if i wanted to sum all values until 6pm in 1 column and all values after 6pm for 1 day how i would write this out.
I know how to write them separately, i.e.
select name, sum(values) as after6
from table
where time > '18:00'
group by name;
select name, sum(values) as upto6
from table
where time < '18:00'
group by name;
how can i combine these to have a columns after6 and upto6 next to each other.
if somebody could please advise.
thanks in advance

Answer 1

Using case you can split the column then sum the column .Try the below
select name,
          SUM(CASE WHEN time > '18:00' THEN values ELSE 0 END) as after6,
          SUM(CASE WHEN time < '18:00' THEN values ELSE 0 END) as upto6  
from table
groupbyname;
